I just completed a "shell on" subfloor replacement in my 1975 Sovereign
. I tore out all of the old, rotted subfloor by cutting the bolts in the C-channel, reinsulated and replace the subfloor with 3/4" new plywood. I was able to complete this with the belly pan on. However, I now need to secure the shell to the chassis.
Is there anyway to attach the frame to the chassis through the subfloor without removing the belly pan? Is it possible to use self tapping screws through the C-channel and into the chassis in order to avoid needing a bolt or is this far too dangerous? Any insight would be appreciated.
